    <p>
      This sample is a simplified version of the <a href="../samples/draggableLink.html">Draggable Link</a> sample.
      Links are not draggable, there are no custom <a>Adornment</a>s, nodes are not rotatable, and links
      do not have text labels.
    </p>
    <p>
      Its purpose is to demonstrate the <a href="SnapLinkReshapingTool.ts">SnapLinkReshapingTool</a>,
      an extension of <a>LinkReshapingTool</a> that snaps each dragged reshape handle of selected Links to
      the nearest grid point.  If the <a>SnapLinkReshapingTool.avoidsNodes</a> option is true,
      as it is by default, then the reshaping is limited to points where the adjacent segments would not
      be crossing over any avoidable nodes.
    </p>
    <p>
      Note how the "LinkReshaped" DiagramEvent listener changes the <a>Link.routing</a> of the reshaped Link,
      so that it is no longer AvoidsNodes routing but simple Orthogonal routing.
      This combined with <a>Link.adjusting</a> being End permits the middle points of the link route to be
      retained even after the user moves or resizes nodes.
      Furthermore there is a TwoWay <a>Binding</a> on <a>Link.routing</a>, so that the model remembers
      whether the link route had ever been reshaped manually.
